| The TDSP™ system is a three pill system designed to efficiently displace drilling mud with minimal mud contamination and fluid interface. It is especially applicable in situations requiring segregation of fluids due to environmental considerations.
The TDSP spacer system requires the pumping of a minimum of the three spacers outlined below. Each spacer is specifically designed by your TETRA fluids specialist to perform one of the three displacement processes and maintain compatibility with the fluids it contacts.
The spacers are designed to perform the following displacement processes:  TDSP I — The Mud Removal Stage
TDSP II — The Surfactant Wash Stage
TDSP III — The Viscosified Sweep Stage
